UNFOLDING OF REFLECTOR CARCASS Russian patent published in 2013 - IPC B64G1/22 H01Q1/28 

FIELD: transport.

SUBSTANCE: invention relates to trussed core transformable structures and may be used in, for example, full-parabolic reflector of space antenna. Reflector carcass comprises forming rod elements, each being composed of two mutually spring-loaded parts hinged together. Hinges are arranged at the ends of said rod elements. Said assemblies, forming and diagonal rod-type elements are used to form two opposite surfaces of full-parabolic reflector. Note also said diagonal elements are articulated to hinges of opposite surfaces. Design of the hinge of every forming rod-type element allows the angle between two parts of said rod-type element a bit smaller than 180 degrees. Said angle is defined by reflector curvature and rod-type forming element length.

EFFECT: higher accuracy of approximating reflection surface to second-order surface, for example, parabolic.
